Addison Bland, 1827 Shelby County, TN

My husband's great great grandfather was Addison Bland, b~1837, Shelby County, TN.He was the son of William (1805 NC) and Zebby Bland.Addison's son Thomas M. Bland (1849-1908) married Mary Ann Jeter and had children Lucille, Addison J., Lottie, Mollie, and Charles Bascom.William was possibly the son of Cornelius Bland.I know that there are Bland Addisons, as well as Addison Blands, but I have not been able to document how the families connect.Martha Ann Bland
